7.6.12.1 NO Working Standard Traced to NIST NO Standard

First, use the NIST-traceable NO standard and the GPT calibration procedure to calibrate the NO, NOx, and NO2 responses of the analyzer. Also determine the efficiency of the Molycon. Refer to the calibration procedure described in Section 7.6.4.2.

Then, generate several NO concentrations by diluting the NO working standard. Use the nominal NO cylinder concentration, [NO]NOM, to calculate the diluted concentrations. Plot the analyzer NO response (in ppm) versus the nominal diluted NO concentration and determine the slope, SNOM. Calculate the NO concentration of the working standard [NO]STD from:

[NO]STD = [NO]NOM x SNOM

A procedure is presented in the TAD in Reference 2.

7.6.12.2Other Methods of Establishing Traceability

They are:

1.NO working standard traced to NIST NO2 standard

2.NO2 working standard traced to NIST NO2 standard

3.NO2 working standard traced to NIST NO2 standard

NOTE

For further information on calibration by GPT and NO2 permeation devices, refer to part 50 of Chapter 1, Title 40 CFR, Appendix F (revised December 1, 1976) and Reference 13 of that Appendix.

7.7 Calibration of Independent Ranges or Autoranging

There are additional considerations when AutoRange or Independent Ranges are selected. The M200AU uses one physical range of 0-2000 ppb to cover all EPA concentration ranges. The dynamic range of the internal hardware and computer software is sufficient to cover this entire range. Internally the range only scales parts of the 0-2000 ppb physical range to cover the voltage range selected for the analog outputs.

7.7.1 Zero Calibration with AutoRange or Independent Range

Having one physical range to cover all EPA concentration ranges simplifies zero calibration. No matter what AutoRange or Independent Range values are selected the values computed from a zero calibration are the same. Therefore no special precautions need to be taken when doing a zero calibration.
